I have a 2004 Corsa 1.4I Utility, the bakkie keeps on over reffing, it seems to be fine when you start it and then the refs picks up and stays on about 2500 sometimes goes up to 3000, does anyone have the same problem and what can we do to fix this problem.
I have a 2008 Opel corsa. Had the same problem. Clean the idle throttle valve on your inlet manifold. You need a special star type screwdriver. There are 2 screws holding it. Has a spring type mechanism that opens and closes when warm. Spray Chromoly cleaner in this (lots) and let it drip dry. Clean and spray dirt away...Put it back and hopefully problem solved...mine was..
